Referring to the accompanying drawings,

we provide a suitably shaped rescue bell 1,v

which if necessary may be used to supplenient the main operating cable10 for raising and lowering the rescue bell. We provide' suitable'braces 4 extending from the top of the post 2 to the upper portion ofthe rescue bell 1, as shown in Fig. 3.

Slidably mounted on the rescue bell are a plurality of horizontal arms 5slidably mountedon the post 2 between the top 6 of the rescue bell andthe annular lange 7 on` post 2. lVe provide rods or cables 8 extendingfrom the horizontal arms 5 to a ring 9 to which an operating rope orcable 1() is attached, and which may also be used for raising andlowering the bell. Secured to the ends of the horizontal arms 5 are rods11 which are pivotally connected to the upper supporting arms and areslidably mounted in spaced apertured braces 12 and pivotally connectedat their-.lower ends to clamps 13, which in turn are pivotally mountedin a suitable manner7 as by brackets 14, on the lower end of the rescuebell.

XVe provide suitable springs 15 arranged to exert resilient pressuredown on clamps 13. Positioned near the lower end of the rescue bell isan annular platform or floor 16, as shown in Figs. 5 and 7, threaded asat 17 to releasably engage the circular screw threaded door 1S. le alsoprovide a plurality of clamps o1 releasably engaging the door 18 to giveincreased protection against deep water pressure. lVe provide a suitablehandle 19 for operating door 18, and may provide a suitable gasket 2O tomake a watertight closure.

le provide suitable and preferably approximately S15-shaped locks orbolts 21, which may be provided with collars 22 resting on the floor 16.These locks are operable from within the rescue bell and are adapted toengage the annular-ly flanged anchoring ring y23 which is integral withor aiiixed to the door 25. Spaced from the anchoring ring 28 is a secondanchoring ring 26 having an outturned annular flange 27 adapted to beengaged by the hook ends of clamp 13.

We provide a suitable gasket or resilient `ring 28 resting ontheannular. flange 27 of `the anchoring ring26. The ring 26 which isintegral with or affixed tothe hull of the submarine is spaced from theanchoring ring 23 sulliciently to just receive the lower end 'oftherescue bell in the manner illustrated in Fig. 7 of the drawings. lealso prefer to provide a suitable door 29 to permit convenientaccesss'tov theinterior@ ofthe bell i through the side Wall thereof andwe may' provide one ormoresuitable ports' or wins'- dows 30 in the wallofthe rescue bell, as

shown in Fig. 3. l/Ve' provide suitable iieirible air. pipe or conduit32 through whichair. may bepumpedto the interiorof the bell yiivhe'nthe'bell'is long submerged'. l

The mode ofoperation of .the invention is illustrated in Figs. land 2rof the drawings.

The rescue bell is lowered by the yoperating ropes-r `cable lO'whi'chisVattached to ring 9 to y.which in turn the 'rods 'or .cables 8 aresecured, vthese Vrods or cables in turn being secured tothe horizontalarm V 5 slidablyy mounted on the post 2, yas shown in Fig. 3,

kand to Vthe' ends of which armsv the roidskll .are pivotally attached,-ythe rods 1l in turn being attached, at their lower end to the pivted:clamps which yare yheld in a raised :position so that when the rescuebell comes in contact with any one ofthe three safety ports A, B,y.or C,the ybottom portion of the bell mayfseat .over this port in the mannershown in Fig. 2, the operating rope or cable being lowered to allow thespring controlled clamps .to engageiunder. the annular flange 27 of theVanchoring ring 26 .whichA is integral withor affixed tothe lhu'll of thesubmarine. 'lheIS-shaped blocksl or bolts-22 are swung into engagementwith the inner anchoring ring 23, 'as shownk inFig. 7. The' screwthreaded ldoor 18 is removed from its' seat and the door 3l ofv port 24is opened, thus aifordingaccess of the imprisoned passengers of thesunkengsubmarine to the rescue-bell.

' The door Slmayv then beclosed, the door -18 replacechthe locks orbolts 21.1eleased and the rescue bell elevated by means of the lmainicable 3 which is yattached securelyto the post 2 at the top 'of therescue bell.

Itis our belief that three or--four'resting platforms 'A,YBY and C canbe placed in such positions on the submarine so that in no matter whatposition the submarinemight lieA a contact could reasonably'be madeespecially with the assistance of divers Vto assist indirectingoperations. t is within-the-contemplation of our invention thatmeans for directing contact'of ythe rescue bell with one of theresting'platforms may be accomplished by a suitable means not disclosedVinV this speciiication, without theassistance .of divers.

What we claim is: 1. ln an apparatus of the class described adapted foruse with a submarine having atlattaching the cable to the upper end ofthe rescue bell, spring actuated clamps mounted on the lower end of therescue bell and adapted to engage suitable attachment means on thesubmarine, and means operativelyconnected withv said clamps forcontrolling them from a point` above the surface of the water.

2.,V A :rescuef bell for useV on s submarines, comprising a cylindricalstructure having a posta-Ontheanpper .end thereof to which a cable maybe attached, pivoted spring actuated Aclampsmounte'dffon the lower endthereof'and adapted to engage. .an attachment member on the hullof thesubmarine, rods attached to said clamps, and meansoperatively'connecting saidrods with a cable adapted to'be'l operatedfrom a pointabove the surface of the/water to control the action'of theclamps, 'and a water-tight doorin thelower portion 'ofthe rescue'gbelladapted vto be `opened from within theres'cue belly after it has beenattached to the'. hull ofthev submarine over a port thereof.. 'A ,f

'3. In' an apparatus cftheclass described, the'rcombination with a'submarine ofmeans for securing a rescue bell` tothe Vhull of same overa port of the submarine, saidl means comprlsmg anV inwardly VturnedL-shaped ring' encirclingzthe port and havingan annular flange, anoutwardly turned L-shaped ring encircling the iirst ring and spaced fromit a A'carried by the rescue bell.

Y 4. In an apparatus of the classdescribed, thev combination withl asubmarine-of means for securing a rescue bell to the Vhull-fof same overa port of the submarine, said means comprising an inwardly turned"L-shaped' ring ,encircling the port' andl having an annular flange, anoutwardly turned L-shapedring encircling the iirst vring and spaced fromit a'suliicient distance to snugly. receive the lower end of therescue'bell therebetween, each of said elementsbeing` adapted to beengaged by fastening means carriedV by the resl cue bell. Y l

5. In a rescue device for use on sunken submarines comprising la rescuebell, means for lowering the rescue'bell, reversely faced L- shapedrings spaced apart to receive the lower end of the rescue bell, saidrings being affixed to or integral with the hull Aof the submarine andencircling ports thereof, and means carried by the rescue bell andoperable 'from a point above the water for clamping the rescue bell tothe outer ring, and means .operl able from within the rescue bell forattachingit to the inner ring, and an airtight door the bottom portionof the rescue bell.
